How long can clothes be left in the washer before they sour?

Leaving clothes in the washer for up to one day can lead to souring due to the growth of bacteria and mildew in damp, warm environments. The duration of time that clothes can safely stay in the washer without developing an unpleasant odor is limited; while some may argue for longer periods, up to a full day is generally recognized as a maximum. After extended periods, especially in warm conditions, the risk of fabric deterioration and unwanted smells increases significantly.

In practice, it's advisable to remove clothes promptly after the wash cycle ends. Regular washing machine maintenance and ensuring clothes are dried properly can also mitigate any souring or mildew issues. Understanding these details can assist in maintaining the freshness and quality of laundry over time.
